Question

What happens when the small subunit of the ribosome encounters an mRNA?

(a) Separation of the small and the larger subunit of the ribosome

(b) Translation of the central dogma of DNA

(c) Joining of the small and the larger subunit of the ribosome

(d) Transcription of the central dogma of DNA

This question was posed to me in a job interview.

My question is based upon Molecular Basis of Inheritance in portion Molecular Basis of Inheritance of Biology – Class 12

Answer 1

Correct answer is (b) Translation of the central dogma of DNA

For explanation: The central dogma of DNA occurs in its 2 stages. They are transcription and translation. When the small subunit of the ribosome encounters an mRNA, the process of translation commences. The process of translation from the mRNA to the proteins occur.
